A novel package is formed from (a) a multilayer thermoplastic film (2) with abutted ends, including a first welded layer (8) and a second partially or non-butt weldable layer (7) and (b) at least one thin strip (6) covering the ends of the film, directly fixed to a surface of the second layer. The difference in m.pt. between the first layer of the laminate and the other layer(s) is more than 20[deg]C. An independent claim is included for the production of the package by butt-welding the edges of the multilayer film (2), where the edges of the film are abutted, heated and cooled to carry out the welding, followed by fixing the strip(s) (6) to the second layer (7) to cover the ends. |
